How Croatia VAT numbers are built

HR followed by 11 digits, the OIB personal identification number.

Check digit

The 11th digit is a check digit (ISO 7064 MOD 11,10). The validator checks it.

Common mistakes

Every person and company in Croatia has an OIB; only VAT-registered ones are valid in VIES.

Is the number registered?

A valid format and check digit only mean the number could exist. Whether it is currently registered for VAT is known to the Tax Administration (Porezna uprava), and VIES asks that register for you. Where Croatia shares them, VIES also returns the registered name and address.
